I have a Stingray 5 and when the OLP's first came out in UK I tried one.

IMHO and on limited experience ie the one I played, the problem is the sound. It played ok, the B was not floppy again IMHO. The OLP 5's have passive tones for each coil of the pickup. It didnt sound bad but it didnt have that "bottom and top" sound that mine has.

If you factor in adding actives and maybe changing the pup it gets expensive. Try one and try a MIM deluxe Jazz as well.

I used to a own a four, and slapped a decent pup and pre-amp (pre-used from a EB Stingray) and it sounded okay. I sold it on, within about a month, but it played great for such a cheap bass, and was way better than say a Squire Precision!! If you are on a budget and can only afford a cheap bass, or are just looking for a cheap one, I would say it makes a good "project bass" for defretting or modyfying. Though, they are no comparison to EBs in quality or finish. And yes, those 5s are bad, the spacing seems wrong as well as a truly appalling B.
